clear
暸 centers on clarity and brightness, like a clear day or a clear understanding. The single given meaning 'clear' covers both visual and mental clarity.
暸 combines 日 (sun) with 尞, which likely contributes the sound and may relate to brightness or height. The exact historical development of 尞 is uncertain, but the character is used to express clarity.
The sun 日 on the left shines on the right side 尞, which looks like a tall structure with a fire on top. Imagine a bright, clear day where the sun illuminates everything, making details sharp and clear.
For リョウ, imagine a clear, bright day in Rio de Janeiro: Rio -> リョウ, and the sun makes everything perfectly clear.
